…It took a couple of leisurely hours to build and glue,
and with supervision was surprisingly easy to make. It can be assembled
inexpensively using wooden pencils ($5.74 for 72), a few rubber bands
and a little superglue, in pretty much exactly the same way as Alejandro
makes his Hexastix sculptures… The hexagonal cross-section of the
pencils make them a very natural fit for this geometric form, as the
holes in the lattice are themselves hexagonal. The erasers are arranged
tetrahedrally with respect to one another; the volume enclosed by the
pencils is a rhombic dodecahedron.
